Answer :

Let's evaluate the expression [tex]\( 4xz - 12xy \)[/tex] given the values [tex]\( x = 2 \)[/tex], [tex]\( y = 3 \)[/tex], and [tex]\( z = 4 \)[/tex].

1. Substitute the values into the expression:

[tex]\[ 4xz - 12xy = 4 \cdot 2 \cdot 4 - 12 \cdot 2 \cdot 3 \][/tex]

2. Calculate the first term [tex]\( 4xz \)[/tex]:

[tex]\[ 4 \cdot 2 \cdot 4 = 4 \cdot 8 = 32 \][/tex]

3. Calculate the second term [tex]\( 12xy \)[/tex]:

[tex]\[ 12 \cdot 2 \cdot 3 = 12 \cdot 6 = 72 \][/tex]

4. Subtract the second term from the first term:

[tex]\[ 32 - 72 = -40 \][/tex]

Therefore, the value of the expression [tex]\( 4xz - 12xy \)[/tex] is [tex]\(-40\)[/tex].
